CWA 8×170 to 8×200 Wheel Adapter 2″ Inch (Ford RAM Dually)
The CWA adapter converts 8×170 bolt patterns to the 8×200 setup commonly used on Ford Super Duty and RAM duallies. It is designed for heavy-duty use with grade 12.9 studs and includes two adapters per set. Suitable for maintaining stability when removing a dual rear wheel configuration, these adapters emphasize compatibility and safety during a wheel conversion project.
8 to 10 Lug Dually Wheel Adapter
Goeske’s 8 to 10 Lug Dually Wheel Adapter expands compatibility for a variety of duallies, offering a practical bridge when moving to a single-wheel arrangement. The design focuses on secure mounting and consistent hub alignment to minimize wobble or misfit, a critical factor when reconfiguring heavy-duty wheels. Check lug count compatibility for your specific vehicle model before ordering.
CWA 8×170 to 8×200 Wheel Adapter 2″ Inch (Set of 2)
This pair of CWA adapters facilitates a robust 2″ offset while converting 8×170 to 8×200 bolt patterns. Featuring Grade 12.9 studs, these adapters are engineered for heavy-duty trucks facing high load demands. Ensure proper alignment with your wheel and hub geometry for a secure installation.
CWA 8×170 to 8×200 Wheel Adapters (Set of 2)
Another variant from CWA, these adapters also convert 8×170 to 8×200 with a 2″ offset and come in a two-piece set. The included Grade 12.9 studs provide rigidity and resistance to torque during aggressive driving. Verify vehicle compatibility and clearance with brake components and fenders to avoid interference.
Tevlaphee Universal Wheel Lock
The Tevlaphee wheel lock offers an optional security layer during the conversion, deterring wheel theft with a bright, highly visible finish. It supports a broad wheel width range (7 to 11 inches) and uses a strong steel locking mechanism. Consider using a wheel lock in conjunction with adapters when reconfiguring a duallie to a single-wheel setup, especially in unsecured parking areas.
Buying Guide
Key considerations when converting a dually to a single wheel focus on fitment accuracy, safety margins, and long-term durability. Below are practical factors and comparisons to help you decide which adapters to choose.
- Bolt pattern compatibility: Confirm that the adapter matches the hub pattern (e.g., 8×170 to 8×200) and verify any required offset. Incorrect bolt alignment can cause vibration and uneven tire wear.
- Vehicle make and model: Ensure the adapter is designed for your specific truck, whether Ford Super Duty, RAM, or other heavy-duty variants. Some adapters are grade-rated for 12.9 studs to handle high torque.
- Offset and clearance: A 2″ offset is common, but verify that there is adequate clearance between the new wheel, brake calipers, and fenders to prevent rubbing during steering and suspension travel.
- Strength and materials: Look for adapters with high-strength steel, precision machining, and properly rated studs. Grade 12.9 studs indicate superior load handling and reliability for heavy-duty applications.
- Installation and torque specs: Follow manufacturer torque specs to prevent over-tightening or loosening under load. Proper hub mounting is essential for safe operation with single-wheel configurations.
- Security: If you park in unsecured areas, consider adding a wheel lock to deter theft during and after the conversion process.
- Legal and insurance considerations: Check local regulations and insurer policies regarding wheel conversions, as some jurisdictions have strict requirements for aftermarket adapters.
- Long-term maintenance: Periodically inspect adapters for cracks, corrosion, or seal damage. Re-torque according to recommendations, and replace any worn components promptly.
- Cost vs. benefit: Compare the total cost of adapters, studs, potential brake clearance issues, and installation time against the expected gains in fuel efficiency and simpler maintenance.
Overall, selecting adapters with robust construction, correct bolt patterns, and proper offset is essential for a safe and reliable conversion. Always verify compatibility with your brake system, axle type, and wheel dimensions before purchase, and consider professional installation if you are unsure about torque specifications or alignment.
